Specification of Letters Patent.

Patented oct, 3o, 1906.

Application led January 13,1905. Serial No. 240,909.

To all whom, bm/(Ly concern:

Be it known that I, lCHARLES A. LIND- s'rRM, of Allegheny, Allegheny county, Pennsylvania, have invented a'new and useful Body-Bolster, of which theollowing is a full, clear,v and eXact description, reference being had to the `accompanying drawings, forming part of this specification, in which- Figure 1 is a side elevation, partly in section, of my improved bolster. Fig. 2 is a cross-section on the line II II of Fig. 1. Fig. 3 is a top plan view, and Fig. 4 is a partial sectional elevation showing a modiiied form.

My invention relates to the class of bodybolsters for cars, and is designed to provide a cast compression member and a wrought tension member, both of said members being below' the longitudinal car-sills.

In the drawings, referring to the form of Figs. 1 to 3, inclusive, 2 represents the compression member, which is cast, preferably, in

substantially U-shaped cellular form and tapered from its center toward the ends. 3 is the horizontal tension member, having its ends bent around the thickened web portions 4 of the compression member and secured by rivets 5. The tension member 3 extends below the longitudinal car-sills, which in this form are shown at 6, the side bearings being shown at 7.

In Fig. 4 I show the compression member as cast with openings or holes to receive the draft-sills, (shown at 8,) these draft-sills eX- tending through the compression member.

The advantages of my invention result from using a cast compression member and a Wrought tension member, both of which are below the longitudinal sill of the car. A simple, strong, and effective structure is thus provided which does not interfere with the framing.

I claim- ,f

l. A body-bolster, comprising a cast compression member castein cellular form and formed with intermediate supports for a tension member, and a horizontal tension member having its end portions bent around and secured tothe end portions of the compression member g substantially as described.

2. A body-bolster comprising a cast Gompression member, cast in cellular form, with a plurality of horizontal supports for a ten sion member, and having its lower surface inclined upwardly and outwardly from the center, and a horizontal tension member resting upon said supports and secured to the compression member at its ends; substantially as described.

3. A body-bolster arranged below the carsill, said bolster being cast in cellular form in cross-section with a plurality of upwardlyextending intermediate supports for a tension member, and having holes to receive draft-sills; substantially as described.

4. A b`ody-bolster havingr a cast compression member of substantially U-shaped crosssection provided with intermediate supports, and a wgmghi tension member secured to Athe compression member and resting upon said supports 5 substantially as described.

5. Abody-bolster having a cast compression member of substantially U-shaped cross-section provided with intermediate flanged supports, and a wrpghttension member secured to the compression member and resting upon said supports 5 substantially as described.

In testimony whereof I have hereunto set my hand.
